Referring to fig. 1 to 21, an electrical connector 100, a mating electrical connector 300 and an electrical connector assembly according to a first embodiment of the present invention are shown. The electrical connector 100 includes an electrical connector body 101, an outer jacket 200, an inner mold 20, and an outer mold 30.
Referring to fig. 1 to 12, the electrical connector body 101 includes a metal housing 60, a terminal module 70 accommodated in the metal housing 60, a conductive terminal 78 disposed on the terminal module 70, a circuit board 80 electrically connected to the conductive terminal 78, and a cable 90 disposed at a rear end of the circuit board 80 and electrically connected to the circuit board 80. The terminal module 70 includes a first terminal module 71 and a second terminal module 72, and one of the first terminal module 71 and the second terminal module 72 is provided with a butt tongue plate 75 extending forward in the butt direction. The terminals 78 are held to the terminal module 70 and are provided with solder feet 781 that are soldered to the circuit board 80. The soldering feet 781 are located at the rear ends of the first terminal module 71 and the second terminal module 72 and soldered to the circuit board 80. The second mating portion 10 of the electrical connector 100 is formed by the mating tongue plate 75 of the terminal module 70 surrounded by the metal housing 60 at the front end of the electrical connector body 101. There is a certain gap between the butt-tongue plate 75 and the periphery of the metal housing 60, and an annular butt-joint chamber 113 is formed between the butt-tongue plate 75 and the metal housing 60. The front end surface of the second abutting portion 10 is provided with an abutting end surface 11. The metal shell 60 is provided with an open hole 65 near the butt end face 11. The electrical connector main body 101 further includes an outer housing 40 fastened to the rear end of the metal housing 60 and covering the front ends of the circuit board 80 and the cable 90. The outer housing 40 is composed of an upper housing 41 and a lower housing 42 mated therewith.
The outer sleeve 200 is separately formed and then sleeved on the second mating portion 10 of the electrical connector 100. The jacket 200 includes a first portion 211 and a second portion 221 connected to the first portion 211, and the radial dimension of the first portion 211 is greater than the radial dimension of the second portion 221, i.e., the cross-sectional dimension of the first portion 211 is greater than the cross-sectional dimension of the second portion 221. This forms a stepped end surface 210 between the first portion 211 and the second portion 221. The step end surface 210 is perpendicular to the front-rear direction. The jacket 200 has a front end surface 241, a rear end surface 242, and a receiving space penetrating the front end surface 241 and the rear end surface 242. The outer surfaces of the first portion 211 and the second portion 221 of the sleeve 200 are each provided with a plurality of recesses 215. The second portion 221 of the outer sleeve 200 is sleeved on the second mating portion 10 of the electrical connector 100, so that the first portion 211 of the outer sleeve 200 forms a receiving cavity 230 with a front end communicating with the outside at the front end of the second mating portion 10. The accommodating chamber 230 is provided therein with a reinforcing portion 231 protruding toward the accommodating chamber 230. The reinforcement parts 231 are disposed in the receiving chamber 230 in a vertically symmetrical manner. The reinforcement 231 is elongated, and the longitudinal direction extends perpendicular to the abutting direction. The inner surface of the receiving space of the second portion 221 of the outer sleeve 200 is provided with a relief portion 260 corresponding to the opening 65 of the metal housing 60, and the relief portion 260 is recessed from the inner surface of the second portion 221 of the outer sleeve 200, but does not penetrate through the inner and outer surfaces of the second portion 221 of the outer sleeve 200. The sleeve 200 is sleeved on the second mating portion 10 of the electrical connector 100, so that the overall structural strength of the second mating portion 10 is also increased.
The inner mold 20 is integrally formed and covers the second portion 221 of the outer jacket 200 and the exterior of the electrical connector 100. The front end surface of the inner die 20 is coupled with the stepped end surface 210 of the outer jacket 200, and the outer surface of the inner die 20 is flush with the outer surface of the first portion 211 of the outer jacket 200, i.e., the outer surface of the inner die 20 is flush with the outer surface of the first portion 211 of the outer jacket 200. The depressions 215 of the outer surface of the second portion 221 of the outer jacket 200 increase the strength of the bond of the inner mold 20 to the outer jacket 200. The second portion 221 of the outer sleeve 200 sleeved on the second mating portion 10 of the electrical connector 100 also serves as a sealing compound, preventing the compound from entering the interior of the electrical connector through the opening 65 in the metal shell 60 when the inner mold 20 is formed.
The outer mold 30 is integrally formed and wrapped around the first portion 211 of the outer jacket 200 and the outer portion of the inner mold 20 and the front portion of the cable 90 such that the outer mold 30 encloses the outer jacket 200 and the inner mold and the electrical connector body 101 as a single unit. The recess 215 in the outer surface of the first portion 211 of the outer sleeve 200 increases the strength of the bond of the outer sleeve 200 to the outer mold 30. The hardness of the material used for the outer mold 30 is smaller than that of the material used for the outer sleeve 200, and the material of the outer mold 30 can be selected to be various according to the requirements on appearance and hand feeling, such as PVC or TPE.
Referring to fig. 13 to 17, a mating electrical connector 300 according to the present invention is shown, wherein the mating electrical connector 300 includes a mating electrical connector body 310 and a body portion 330.
The mating electrical connector body 310 includes a housing 360, a terminal module accommodated in the housing 360, a terminal 363 disposed on the terminal module, a mating electrical connector circuit board 380 electrically connected to the terminal 363, a mating electrical connector cable 390 electrically connected to a rear end of the mating electrical connector circuit board 380, and a wire block 391. The main body 310 of the mating electrical connector further includes a metal outer shell 340 fastened to the rear end of the shell 360 and covering the circuit board 380 and the whole wire block 391 of the mating electrical connector and the front end of the cable 390 of the mating electrical connector. The metal outer case 340 is composed of an upper case and a lower case mated therewith. The terminals 363 include an upper row of terminals and a lower row of terminals. The first mating portion 311 of the mating electrical connector 300 is formed by surrounding the terminal module with the metal housing 60 at the front end of the electrical connector body 101. A mating cavity 313 is formed in the housing 360 between the upper row of terminals and the row of terminals for receiving the mating tongue 75 of the electrical connector 100. The housing 360 is provided with outwardly protruding fasteners 315, the fasteners 315 mating with corresponding openings 65 in the electrical connector 100.
The body 330 at least comprises a first body 331 and a second body 333 smaller than the first body 331, and the second body 333 has a recess 334 on an outer surface thereof for mating with the protruding reinforcement 231 in the receiving cavity 230 of the electrical connector 100. The body 330 is wrapped around the mating electrical connector body 310 and the first mating portion 311 of the mating electrical connector 300 extends forward beyond the second body 333.
Referring to fig. 18 to 21, in order to illustrate the assembly of the electrical connector 100 and the mating electrical connector 300 according to the present invention, the radial dimension of the receiving cavity 230 of the electrical connector 100 is larger than the radial dimension of the first mating portion 311 of the mating electrical connector 300, that is, the dimension of the receiving cavity 230 perpendicular to the mating direction is larger than the dimension of the first mating portion 311 perpendicular to the mating direction, so that the first mating portion 311 can pass through and mate with the second mating portion 10 behind the receiving cavity 230. The size of the receiving cavity 230 is matched with or larger than the shape of the second body 333 of the mating electrical connector 300 to receive the second body 333. When the electrical connector 100 is mated with the mating electrical connector 300, the first mating portion 311 of the mating electrical connector 300 first passes through the receiving cavity 230 of the electrical connector 100 and then is received in the annular mating cavity 113 of the second mating portion 10 of the electrical connector 100, and at the same time, the mating tongue plate 75 extends into the mating cavity 313 of the mating electrical connector 300, and the second body portion 333 is received in the receiving cavity 230. The protruding reinforcing portion 231 in the receiving cavity 230 is snapped with the corresponding recess portion 334 on the mating electrical connector 300, thereby increasing the mechanical connection strength of the electrical connector 100 after mating with the mating electrical connector 300. The external dimensions of the outer mold 30 of the electrical connector 100 are identical in the height direction and the width direction to the external shape of the second body portion 333 of the mating electrical connector 300, so that when the electrical connector 100 is fully mated with the mating electrical connector 300, the external surfaces of the electrical connector 100 and the mating electrical connector 300 are fully identical in the width direction and the thickness direction, i.e., the external surfaces of both are flush in the mating direction. In the present embodiment, the number of the reinforcing portions 231 and the recessed portions 334 is 2, and the reinforcing portions 231 and the recessed portions 334 are respectively disposed on the receiving cavity 230 of the electrical connector 100 and the second body portion 333 of the mating electrical connector 300, however, the reinforcing portions 231 and the recessed portions 334 may also be replaced with each other, that is, the recessed portions 334 are disposed in the receiving cavity 230 of the electrical connector 100, and the reinforcing portions 231 are disposed on the second body portion 333 of the mating electrical connector 300. The number of the reinforcing parts 231 and the recessed parts 334 may be set to one or more according to the need. In addition, in the present embodiment, the reinforcing portion 231 is mated with the recess portion 334, and the mechanical connection strength of the electrical connector 100 and the mating electrical connector 300 after being mated may be increased by directly interference-mating the housing cavity 230 with the second body portion 333 or other mating methods.

The electrical connector body 101 is identical to the electrical connector body 101 of the first embodiment.
The outer sleeve 52 is integrally formed on the outside of the electrical connector body 101, and the outer sleeve 52 extends forward beyond the mating end face 11 of the electrical connector 100, so that a receiving cavity 530 is formed at the front end of the second mating portion 10, and the front end of the receiving cavity 530 communicates with the outside. The accommodating cavity 530 is provided with a reinforcing part 531 protruding to the accommodating cavity 530. The reinforcing portion 531 is elongated and extends in a longitudinal direction perpendicular to the butt direction of the jacket 52. The size of the receiving cavity 530 matches with or is larger than the shape of the second body 333 of the mating electrical connector 300, so as to receive the second body 333 of the mating electrical connector 300, and when the electrical connector 100 is mated with the mating electrical connector 300, the reinforcing portion 531 is snapped with the corresponding recess 334 on the mating electrical connector 300, thereby increasing the mechanical connection strength of the electrical connector 100 and the mating electrical connector 300 after mating.
The spacer 50 is provided with a front end face and a rear end face, the front end face and the rear end face are mutually communicated, and the spacer 50 is sleeved on the second butting portion 10 of the electric connector 100 after being independently molded, so that the spacer 50 is positioned in the middle layer between the outer sleeve 52 and the second butting portion 10 of the electric connector 100. The outer surface of the spacer 50 is provided with a plurality of recesses 550 to increase the bonding strength of the spacer 50 to the outer jacket 52. The inner surface of the spacer 50 is provided with a relief 560 at a position corresponding to the opening 65 of the metal housing 60 for accommodating the fastener 315 on the first mating portion 311 of the mating electrical connector 300 when the electrical connector 100 is mated with the mating electrical connector 300. The relief 560 is recessed from the inner surface of the spacer 50 but does not extend through the inner and outer surfaces of the spacer 50. The spacer is sleeved on the second butt joint part 10 of the electric connector 100 to play a role of sealing glue, so that the glue is prevented from entering the electric connector 100 through the opening hole 65 on the metal shell 60 when the outer sleeve 52 is formed. The spacer 50 is sleeved on the second mating portion 10 of the electrical connector 100 to also increase the structural strength of the second mating portion 10.
The outer mold 53 is integrally formed and coated on the outer portion of the outer sleeve 52, and the outer mold 53 is made of various materials, so as to meet the requirements on appearance and hand feeling.
In the above two embodiments of the electrical connectors, the front ends of the electrical connectors 100 and 500 are provided with the accommodating cavities 230 and 530, when the electrical connector 100 is mated with the mating electrical connector 300, the corresponding concave portions 334 of the mating electrical connector 300 are buckled by the reinforcing portions 231 and 531 in the accommodating cavities 230 and 530, so as to increase the mechanical connection strength of the electrical connector 100 after being mated with the mating electrical connector 300, and meanwhile, the electrical connector 100 and the mating electrical connector 300 are also interference-mated through the opening hole 65 and the fastener 315, and the two mating modes are combined with each other, so that the overall toughness and the connection strength of the whole product are further increased. Of course, if the mating electrical connector 300 is not provided with the fastener 315, the mechanical connection strength of the electrical connector 100 after being mated with the mating electrical connector 300 can be increased only by providing the reinforcing portions 231, 531 in the receiving cavities 230, 530 of the electrical connector 100 to mate with the corresponding recess 334 on the mating electrical connector 300. By the above implementation, the electrical connector 100 and the mating electrical connector 300 can be directly plugged and unplugged without an unlocking device. The operation is simple and the use is convenient.
The foregoing is only some, but not all, embodiments of the present invention, and any equivalent modifications of the technical solution of the present invention will be covered by the claims of the present invention by a person of ordinary skill in the art from reading the present specification.
